Device, method, and graphical user interface for outputting captions

ABSTRACT

An electronic device outputs a first caption of a plurality of captions while a first segment of a video is being played, where the first video segment corresponds to the first caption. While outputting the first caption, the device receives a first user input. In response to receiving the first user input, the device determines a second caption in the plurality of captions, distinct from the first caption, that meets predefined caption selection criteria; determines a second segment of the video that corresponds to the second caption; sends instructions to change from playing the first segment of the video to playing the second segment of the video; and outputs the second caption.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/783,540, filed on Mar. 14, 2013, entitled DEVICE, METHOD, AND GRAPHICAL USER INTERFACE FOR OUTPUTTING CAPTIONS, which is hereby incorporated by reference in its entity for all purposes.

TECHNICAL FIELD

This relates generally to electronic devices, including but not limited to electronic devices that output captions for movies and other video content.

BACKGROUND

The use of electronic devices to receive and/or stream content, such as videos, has increased significantly in recent years. Further, with the globalization of the market for content, users have more access to foreign video content than ever before. The foreign video content often comes with subtitles, in order to give the user the option of hearing the original speech and intonations in the foreign video content. This foreign video content adds to the wealth of video content that has closed captions, subtitles, or the like that are displayed on screen.

But users who are blind or have low vision are not able to see captions, subtitles, or the like displayed on-screen. Thus, users with impaired vision may have to listen to dubbed speech, which is often inferior to the original speech. This detracts from the users' enjoyment of the content. Further, because blind and low-vision users cannot see the video content, they have difficulty fast forwarding or rewinding through video content using conventional methods.

SUMMARY

Accordingly, there is a need for electronic devices with more efficient and more accessible methods and interfaces for outputting captions. Such methods and interfaces may complement or replace conventional methods for outputting captions. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface, particularly for users with impaired vision.

The above deficiencies and other problems associated with user interfaces for electronic devices are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device).

Device 100 may include one or more optical sensors 164. These components may communicate over one or more communication buses or signal lines 103.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 1A may be implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 102 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, may be controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 may be implemented on a single chip, such as chip 104. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication may use any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 may include display controller 156 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input control devices 116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 112 may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 may also include one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 may also include one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 may be coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices (e.g., refreshable braille display 476, FIG. 4C or 4D) over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices (e.g., refreshable braille display 476, FIG. 4C or 4D) or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 may detect contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

In some embodiments, the speech is produced in accordance with any of a plurality of speaker profiles 196. A speaker profile specifies parameters based on which the speech is produced. In some embodiments, the parameters include one or more of: age, gender, speech rate, and intonation. For example, if a speaker profile specifies a 65-year-old woman, then speech produced from text in accordance with the speaker profile simulates the voice of a 65-year-old woman.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that may be displayed on device 100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 may utilize or call data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers may interact with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens, e.g., coordinating mouse movement and mouse button presses with or without single or multiple keyboard presses or holds, user movements taps, drags, scrolls, etc., on touch-pads, pen stylus inputs, movement of the device, oral instructions, detected eye movements, biometric inputs, button presses on a braille display, and/or any combination thereof, which may be utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user may select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture may include one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also may accept verbal input for activation or deactivation of some functions through microphone 113.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 may include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also may include a keyboard and/or mouse (or other pointing device) 350 and touchpad 355. Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 may optionally include one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1), or a subset thereof. Furthermore, memory 370 may store additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 may store drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1) may not store these modules.

Each of the above identified elements in FIG. 3 may be stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that may be implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces may be implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Phone 138, which may include an indicator 414 of the number             of missed calls or voicemail messages;         -   E-mail client 140, which may include an indicator 410 of the             number of unread e-mails;         -   Browser 147; and         -   Video and music player 152, also referred to as iPod             (trademark of Apple Inc.) module 152; and     -   Icons for other applications, such as:         -   IM 141;         -   Image management 144;         -   Camera 143;         -   Weather 149-1;         -   Stocks 149-2;         -   Workout support 142;         -   Calendar 148;         -   Alarm clock 149-4;         -   Map 154;         -   Notes 153;         -   Settings 412, which provides access to settings for device             100 and its various applications 136; and         -   Online video module 155, also referred to as YouTube             (trademark of Google Inc.) module 155.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Although many of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods may be used for other user interfaces described herein.

FIG. 4C illustrates an exemplary refreshable braille display in conjunction with an electronic device in accordance with some embodiments. In FIG. 4C, refreshable braille display 476 includes multiple cells 552 or 554 (FIG. 5E) and optionally multiple buttons (not shown). Depending on the particular refreshable braille display, the cells have either six dots per cell (e.g., cells 552) or eight dots per cell (e.g., cells 554). Refreshable braille display 476 is connected with electronic device 474 (e.g., device 100, FIG. 1A; device 300, FIG. 3) by wired or wireless communication channel 484. For example, refreshable braille display 476 may be plugged into external port 124 of multifunction device 100. Alternatively, refreshable braille display 476 may be connected with electronic device 474 using one or more wireless communication protocols, such as Bluetooth or Wi-Fi. Electronic device 474 is connected to display 472 separate from electronic device 474 by wired or wireless communication channel 486, which is similar to wired or wireless communication channel 484.

FIG. 4D illustrates an exemplary refreshable braille display in conjunction with an electronic device in accordance with some embodiments. In FIG. 4D, refreshable braille display 476 is connected with the electronic device 475 by wired or wireless communication channel 484. The electronic device 475 (e.g., device 100, FIG. 1A; device 300, FIG. 3) includes display 482 (e.g., display 112 or 300). In FIG. 4D, display 482 is integrated with the electronic device, instead of being separate from the electronic device as in FIG. 4C.

In other words, refreshable braille display 476 can be connected to an electronic device that includes a display integrated with the device (e.g., as in FIG. 4D) or that is connected to a separate display (e.g., as in FIG. 4C).

FIG. 4C (or 4D) illustrates caption 478 displayed on display 472 (or display 482) in accordance with some embodiments. Caption 478 is displayed in conjunction with video content (not shown). The electronic device outputs caption 478 to refreshable braille display 476, which outputs caption 478 in Braille, as caption 480. Thus, caption 478 and caption 480 include the same text; caption 478 is displayed with characters for a certain language, for visual comprehension, and caption 480 is displayed with Braille for tactile comprehension.

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as device 300 or portable multifunction device 100.

FIGS. 5A-5E illustrate exemplary user interfaces for outputting captions in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 6A-6C.

It should be appreciated that, as used herein, “captions” include closed captions, subtitles, or the like. For convenience, they are all referred to collectively as “captions.”

As described above with reference to FIGS. 4C and 4D, the electronic device has an integrated display or is connected to a separate display. For convenience, the embodiments below are described with reference to an electronic device that includes an integrated display (e.g., device 475, as in FIG. 4D). It should be appreciated that the embodiments described below are applicable to an electronic device connected to a separate display (e.g., device 474, as in FIG. 4C).

FIG. 5A illustrates video 502 being played by the electronic device, with the visual component of video 502 being output to display 482. As shown in FIG. 5A, segment 502-1 of video 502 is being played. Video segment 502-1 features speakers 504 and 506.

Video 502 includes video signals and optionally includes audio signals. In some embodiments, when video segment 502-1 is played, the electronic device optionally outputs the corresponding audio signals (e.g., speech that are spoken in video segment 502-1) along with the video signals corresponding to segment 502-1. In some embodiments, when video segment 502-1 is played, the electronic device outputs the corresponding audio signals (e.g., speech that are spoken in video segment 502-1) without outputting the video signals corresponding to segment 502-1.

Video 502 corresponds to multiple captions. A respective caption corresponds to particular speech or a particular scene in a respective segment of video 502. Respective captions are output at various times while video 502 is playing to be concurrent with the corresponding speech or scene in the respective segment. Caption 1 508 corresponds to speech spoken by speaker 504 in segment 502-1; Caption 1 508 corresponds to video segment 502-1.

In some embodiments, the electronic device outputs Caption 1 508 by outputting Caption 1 508 to display 482 for display on display 482. In some embodiments, the electronic device outputs Caption 1 508 for display at a particular location on display 482 (e.g., under speaker 504, the speaker of the speech to which Caption 1 508 corresponds; on the left half, center area, or right half of video 502).

In some embodiments, the electronic device outputs Caption 1 508 by generating and outputting audible voice signals (not shown) corresponding to Caption 1 508. For example, the electronic device, using text-to-speech module 194, converts the text of Caption 1 508 to audible voice signals (e.g., synthesized voice speech). In some embodiments, the device generates the audible voice signals in accordance with a speaker profile. The speaker profile specifies speech parameters (e.g., age of speaker, gender of speaker, speech rate, intonation) that the speech in the audible voice signals simulates. In some embodiments, the speaker profiles are selectable by the user (e.g., preconfigured or on the fly).

The electronic device is optionally connected to refreshable braille display 476. In some embodiments, the electronic device outputs Caption 1 508 by outputting Caption 1 508 to refreshable braille display 476. Refreshable braille display 476 displays Caption 1 508 in braille as Caption 1 510. In some embodiments, refreshable braille display 476 also outputs, in braille, location information 510 and/or speaker information 514 along with Caption 1 510. Location information 510 indicates the location of Caption 1 508 in video 502. Speaker information 514 indicates the identity of the speaker of the speech corresponding to Caption 1 508 (e.g., speaker 504).

The electronic device receives user input 516 (e.g., activation of a button on the refreshable braille display 476, a swipe or tap gesture on a touch sensitive surface, activation of an arrow key on a keyboard, or a voice command). Input 516 directs the electronic device to determine another caption different from Caption 1 508 that meets predefined caption selection criteria.

In some embodiments, input 516 directs the electronic device to determine the next caption different from Caption 1 508 that is displayed at the same location as Caption 1 508. In other words, input 516 directs the electronic device to navigate to the next segment in video 502 that has a different caption that is displayed at the same location as Caption 1 508. Depending on the particular input, the navigation is either forward or backward within video 502.

Input 516 is made by a user using any suitable input device or method associated with the electronic device (e.g., keyboard, mouse, remote control device, touch-sensitive surface, refreshable braille display 476, or voice control). In some embodiments, the user makes input 516 by interacting with a graphical user interface of the electronic device using the above-mentioned input devices or methods.

In response to receiving input 516, the electronic device determines a Caption 2 518, distinct from Caption 1 508, and the segment of video 502 that corresponds to the determined caption. The electronic device changes from playing video segment 502-1 to playing video segment 502-2 and outputs Caption 2 518, as shown in FIG. 5B. Segment 502-2 features speakers 505 and 507. As with Caption 1 508, Caption 2 518 is output by displaying on display 482, by generating and outputting corresponding audible voice signals (not shown), and/or by outputting to refreshable braille device 476.

In some embodiments, when video segment 502-2 is played, the electronic device optionally outputs the corresponding audio signals (e.g., speech that are spoken in video segment 502-2) along with the video signals corresponding to segment 502-2. In some embodiments, when video segment 502-2 is played, the electronic device outputs the corresponding audio signals (e.g., speech that are spoken in video segment 502-2) without outputting the video signals corresponding to segment 502-2.

In some embodiments, when the electronic device outputs Caption 2 518 by generating and outputting audible voice signals (not shown) corresponding to Caption 2 518, the electronic device generates the audible voice signals based on a speaker profile. The speaker profile for Caption 2 518 is, optionally, distinct from the speaker profile for Caption 1 508. For example, a different speaker profile is used for Caption 2 518 if the speaker for the speech corresponding to Caption 2 518 is different than the speaker for the speech corresponding to Caption 1 508.

Refreshable braille display 476 displays Caption 2 518 in braille as Caption 2 520. As with Caption 1 (in braille) 510, refreshable braille display 476 optionally displays in braille, along with Caption 2 (in braille) 520, corresponding location information 522 (analogous to location information 512) and/or corresponding speaker information 524 (analogous to location information 514).

FIG. 5C illustrates the electronic device playing video 526; segment 526-1 being played and is displayed on display 482. The electronic device outputs Caption 3 532, corresponding to segment 526-1, by displaying on display 482, by generating and outputting corresponding audible voice signals (not shown) based on a speaker profile, and/or by outputting to refreshable braille display 476. Segment 526-1 features speakers 528 and 530. Caption 3 532 corresponds to speech spoken by speaker 528 in segment 526-1. Refreshable braille display 476 displays Caption 3 532 in braille as Caption 3 534. Refreshable braille display 476 optionally displays in braille, along with Caption 3 534, corresponding location information 536 and/or corresponding speaker information 538.

Video 526 includes video signals and optionally includes audio signals. In some embodiments, when video segment 526-1 is played, the electronic device optionally outputs the corresponding audio signals (e.g., speech that are spoken in video segment 526-1) along with the video signals corresponding to segment 526-1. In some embodiments, when video segment 526-1 is played, the electronic device outputs the corresponding audio signals (e.g., speech that are spoken in video segment 526-1) without outputting the video signals corresponding to segment 526-1.

The electronic device receives user input 540 (e.g., activation of a button on the refreshable braille display 476, a swipe or tap gesture on a touch sensitive surface, activation of an arrow key on a keyboard, or a voice command). Input 540 directs the electronic device to determine the next caption, different from Caption 3 532, that corresponds to the same speaker (i.e., speaker 528). In other words, input 540 directs the electronic device to navigate to the next segment in video 526 that has a different caption by the same speaker 528 as Caption 3 532. Depending on the particular input, the navigation is either forward or backward within video 526.

Input 540 is made by a user using any suitable input device or method associated with the electronic device (e.g., keyboard, mouse, remote control device, touch-sensitive surface, refreshable braille display 476, voice control). In some embodiments, the user makes input 540 by interacting with a graphical user interface of the electronic device using the above-mentioned input devices or methods.

In response to receiving input 540, the electronic device determines a Caption 4 542, distinct from Caption 3 532, that corresponds to the same speaker 528 as Caption 3 532, and the segment of video 526 that corresponds to the determined caption. The electronic device changes from playing video segment 526-1 to playing video segment 526-2 and outputs Caption 4 542, as shown in FIG. 5D. Segment 526-2 features speaker 528 in a different position than in segment 526-1. As with Caption 3 532, Caption 4 542 is output by displaying on display 482, by generating and outputting corresponding audible voice signals (not shown) based on a speaker profile that corresponds to Caption 3 532, and/or by outputting to refreshable braille device 476.

In some embodiments, when video segment 526-2 is played, the electronic device optionally outputs the corresponding audio signals (e.g., speech that are spoken in video segment 526-2) along with the video signals corresponding to segment 526-2. In some embodiments, when video segment 526-2 is played, the electronic device outputs the corresponding audio signals (e.g., speech that are spoken in video segment 526-2) without outputting the video signals corresponding to segment 526-2.

Refreshable braille display 476 displays Caption 4 542 in braille as Caption 4 544. As with Caption 3 (in braille) 532, refreshable braille display 476 optionally displays in braille, along with Caption 4 (in braille) 544, corresponding location information 546 and/or corresponding speaker information 548.

As described above, refreshable braille display 476 displays captions in braille. Refreshable braille display 476 includes a plurality of cells, with each cell having a number of dots. FIG. 5E illustrates refreshable braille displays 476-1 and 476-2. Refreshable braille display 476-1 includes cells 552-1 thru 552-m. Each cell 552 includes six dots. In some embodiments, when displaying captions and location/speaker information, refreshable braille display 476-1 displays information corresponding to the displayed caption (e.g., location information 512, 522, 536, or 546; speaker information 514, 524, 538, or 548) in a number (e.g., a number between 1-3, inclusive) of cells 552 (e.g., cells 552-1 and 552-2), and displays the characters of the captions in the remainder of the cells (e.g., cells 552-3 thru 552-m). In other words, the cells of refreshable braille display 476-1 is, optionally, subdivided into reserved cells for displaying information corresponding to the captions and cells for displaying the characters of the captions.

Refreshable braille display 476-2 includes cells 554-1 thru 554-n. Each cell 554 includes eight dots. In some embodiments, when displaying captions and location/speaker information, refreshable braille display 476-2 displays information corresponding to the displayed caption (e.g., location information 512, 522, 536, or 546; speaker information 514, 524, 538, or 548) in dots 558 of cells 554 reserved as information dots 558 (e.g., the lower two dots of each cell 554), and displays the characters of the captions in caption dots 556 of cells 554 (e.g., the upper six dots of each cell 554).

In some embodiments, with 8-dot refreshable braille display 476-2, information corresponding to captions is displayed in reserved cells and in information dots 558. For example, location information is displayed in a number of reserved cells (e.g., cells 554-1 and 554-2), the captions are displayed in cells 554-3 thru 554-n in caption dots 556, and speaker information is displayed in cells 554-3 thru 554-n in information dots 558. In some other embodiments, the speaker information is displayed in the reserved cells, and the location information is displayed in information dots 558 in the captions cells. In other words, a combination of the reserved cells strategy (as with refreshable braille display 476-1) and the reserved information dots strategy (as with refreshable braille display 476-2) is used to display captions and corresponding information (e.g., location information, speaker information) on an 8-dot refreshable braille display.

FIGS. 6A-6C are flow diagrams illustrating a method 600 of outputting captions in accordance with some embodiments. The method 600 is performed at an electronic device (e.g., device 474 or 475, which may correspond to device 300, FIG. 3, or portable multifunction device 100, FIG. 1). In some embodiments, a display is integrated with the electronic device. In some embodiments, the electronic device is connected to a separate display. Some operations in method 600 may be combined and/or the order of some operations may be changed.

As described below, the method 600 provides a more efficient and accessible way to output captions. The method reduces the cognitive burden on a user, thereby creating a more efficient human-machine interface, particularly for users with impaired vision.

The device outputs (602) a first caption of a plurality of captions while a first segment of a video is being played, wherein the first video segment corresponds to the first caption. In some embodiments, the plurality of captions includes subtitles. For example, FIG. 5A shows Caption 1 508 output while video segment 502-1 is being played. FIG. 5C shows Caption 3 532 output while video segment 526-1 is being played.

While outputting the first caption, the device receives a first user input (604). For example, the electronic device receives input 516 in FIG. 5A (or input 540 in FIG. 5C) while outputting Caption 1 508 (or Caption 3 532). Exemplary inputs include activation of a button on the refreshable braille display 476, a swipe or tap gesture on a touch sensitive surface, activation of an arrow key on a keyboard, or a voice command.

In response to receiving the first user input (606), the device determines (608) a second caption in the plurality of captions, distinct from the first caption, that meets predefined caption selection criteria; determines (616) a second segment of the video that corresponds to the second caption; sends (618) instructions to change from playing the first segment of the video to playing the second segment of the video; and outputs (622) the second caption. In some embodiments, in response to sending the instructions to change from playing the first segment of video to playing the second segment of video, the electronic device changes from playing the first segment of video to playing the second segment of video. In some embodiments, in response to sending the instructions to change from playing the first segment of video to playing the second segment of video, a display device (e.g., a television or a video player) coupled with the electronic device changes from playing the first segment of video to playing the second segment of video.

For example, in response to receiving input 516, the electronic device determines Caption 2 518, distinct from Caption 1 508, that meets predefined caption selection criteria (e.g., Caption 2 518 occurs at the same location on the display as Caption 1 508) and corresponding video segment 502-2, changes from playing video segment 502-1 to playing video segment 502-2, and outputs Caption 2 518. As another example, in response to receiving input 540, the electronic device determines Caption 4 542, distinct from Caption 3 532, that meets predefined caption selection criteria (e.g., Caption 4 542 has the same speaker as Caption 3 532) and corresponding video segment 526-1, changes from playing video segment 526-1 to playing video segment 526-2, and outputs Caption 4 542.

In some embodiments, the predefined caption selection criteria include (610) that the first caption and the second caption correspond to a same location on a display. In some embodiments, a first set of captions are displayed at a first location (e.g., a first predefined area) on the display and a second set of captions are displayed at a second location (e.g., a second predefined area) on the display that is distinct from the first location. For example, Caption 2 518 is determined on the basis of it being displayed at the same location as Caption 1 508.

In some embodiments, captions that satisfy the predefined caption selection criteria have (612) a sequence, and the first caption is adjacent to the second caption in the sequence. In some embodiments, both the first caption and the second caption correspond to a respective speaker. In some embodiments, the second caption corresponds to speech by the respective speaker immediately subsequent to speech by the respective speaker that corresponds to the first caption among speeches by the respective speaker. For example, Caption 1 508 and Caption 2 518 are adjacent to each other in the sequence of captions displayed at the same location. As another example, Caption 3 532 and Caption 4 542 are adjacent to each other in the sequence of captions corresponding to speech by the same speaker.

In some embodiments, the predefined caption selection criteria include (614) that the first caption and the second caption correspond to a same speaker. For example, Caption 4 542 (FIG. 5D) is determined on the basis of it corresponding to the same speaker as Caption 3 532 (FIG. 5C). In some embodiments, captions corresponding to the same speaker are displayed at the same location (e.g., a predefined area) on the display. In some embodiments, captions that correspond to distinct speakers are displayed at distinct locations on the display. For example, captions that correspond to a first speaker are displayed at a first location on the display, and captions that correspond to a second speaker are displayed at a second location distinct from the first location on the display.

In some embodiments, the video includes (620) video signals and audio signals, and playing the video includes outputting audio signals of the video without outputting the video signals of the video. For example, when video 502 or 526 is being played, the device optionally outputs just the audio signals and does not output the video signals (e.g., video segment 502-1 or 502-2, or video segment 526-1 or 526-1, and the corresponding captions, are not displayed on display 482). In some other embodiments, playing the video includes outputting both the video signals and audio signals of the video.

In some embodiments, outputting the first caption includes (624) outputting a first audible voice signal corresponding to the first caption, and outputting the second caption includes outputting a second audible voice signal corresponding to the second caption. In some embodiments, the electronic device converts a respective caption into an audible voice signal. In some embodiments, the electronic device includes a text-to-speech engine. For example, the device outputs audible voice signals corresponding to Caption 1 508 (FIG. 5A) and audible voice signals corresponding to Caption 2 518 (FIG. 5B). Similarly, the device outputs audible voice signals corresponding to Caption 3 532 (FIG. 5C) and audible voices signals corresponding to Caption 4 542 (FIG. 5D).

In some embodiments, the electronic device is coupled with a display; outputting the first caption includes displaying the first caption on a display; and outputting the second caption includes displaying the second caption on the display.

In some embodiments, the first caption corresponds (626) to a first speaker and the second caption corresponds to a second speaker distinct from the first speaker, outputting the first audible voice signal includes converting the first caption into the first audible voice signal based on a first speaker profile, and outputting the second audible voice signal includes converting the second caption into the second audible voice signal based on a second speaker profile distinct from the first speaker profile. Converting a caption into an audible voice signal is sometimes called synthesized caption output. In some embodiments, a respective speaker profile corresponds to a voice selected by a user. In some embodiments, the respective speaker profile corresponds to a speaker of a respective age and gender selected by the user. In some embodiments, the respective speaker profile corresponds to a speech rate selected by the user. In some embodiments, the respective speaker profile corresponds to an intonation selected by the user. For example, Caption 1 508 and Caption 2 518 are converted by the device to respective audible voice signals using different speaker profiles 196 when speaker 504 is a different person from speaker 505, whereas Caption 3 532 and Caption 4 542 are converted by the device to respective audible voice signals using the same speaker profile 196 because the same speaker 528 is talking in Caption 3 532 and Caption 4 542.

In some embodiments, the electronic device is coupled (628) with a Braille display, outputting the first caption includes sending instructions to the Braille display to output the first caption, and outputting the second caption includes sending instructions to the Braille display to output the second caption. For example, the electronic device is coupled with refreshable braille display 476. The device outputs Caption 1 508 by outputting Caption 1 508 to refreshable braille display 476 for display at refreshable braille display 476, and outputs Caption 2 518 by outputting Caption 2 518 to refreshable braille display 476 for display at refreshable braille display 476. The device outputs Caption 3 532 by outputting Caption 3 532 to refreshable braille display 476 for display at refreshable braille display 476, and outputs Caption 4 542 by outputting Caption 4 542 to refreshable braille display 476 for display at refreshable braille display 476.

In some embodiments, the Braille display is configured (630) to indicate a first location of the first caption and a second location of the second caption. In some embodiments, the first location is distinct from the second location. In some embodiments, the first location is identical to the second location. Refreshable braille display 476 outputs, for example, location information 512 522, 536, or 546 along with Caption 1 508, Caption 2 518, Caption 3 532, and Caption 4 542, respectively.
